3’,4-Dialkylthio-3,4’-diquinolinyl sulfides (6) were obtained by three methods in the reaction of thioquinanthrene (1) with sodium hydrosulfide followed by sequential S-alkylation of the 3- and 4-thiolate functions. Competitive S-alkylation of 3- and 4-qui-nolinethiolates (4) and (10) in DMSO showed three times greater susceptibility of the 3-thiolate function to the alkylating agent than the 4-thiolate function. 4-Quinolinethio-lates (3) were converted into 4(1H)-quinolinethiones (8).
